Swiss powder produces more velocity than Wano in my muzzleloaders. In a .50 cal shooting a round ball, 80 grs of Swiss FF produces the same velocity as 100 grs of Wano FF. I cant find the chronograph notes right now but I think the Swiss powder was shooting around 200 fps faster than Wano with the same charge weight. I dont have any experience with black powder cartridge but I cant imagine being able to damage a Ruger #1 with any amount of black powder.
Both powders seem to produce the same amount of fouling with equal charge weights, the only difference was the color of the fouling.
